[Doege-Potter syndrome. about one new case].

Syndrome Doege-Potter is a paraneoplastic syndrome in which hypoglycemia is the result of tumors producing insulin growth factor-like (IGF-II) it is most often solitary fibrous tumor of the pleura (TFSP). These are rare and may be discovered incidentally, during non-specific respiratory symptoms or during hypoglycemia. Hypoglycemia occurs in tumors of large volume and it disappears after surgery, which is the treatment of choice for a permanent cure in most cases. We present a case of Doege-Potter syndrome whose interest is to consider the TFSP as a cause of hypoglycemia in patients with pleural tumors.
